In Fig. 1 of the drawing, I have'diagrammatically illustrated one methodof carrying my invention into'eifect'and of treating strands of the Inthis figure, Ill rep-1. resents a; reel containing the strand I l tobetiated. In this connection it will be understood that the reference inthe specification to stran will be interpreted to, mean a wire, cotton,silk or other strand or an electric conductor disposed in casings,jackets or sheaths of variohs kinds and classes and including what areknown as 5 cable and electric conduits.

- The strand H from the reel l0 first passes into and through a tank l2containing the saturant, compound or other coating or finishing materialD by first-passing over a sheave l3 at one end of the 0 tank, downwardlyaround a sheave It in the tank and then out of the tank and over asheave l5 from which the strand passes into and through one of myimproved dual wipers or applicators 16. In some instances, the tank 12will have suitable means of heating as indicated at l2a to maintain thedesired temperature for the saturant or compound employed. After passingthrough the wiper it which performs functions and operations laterdescribed, the coated strand 40 passed downwardly intoand through acooling tank IT or under a sheave I8 disposed therein. Cooling waterl'liz is introduced into the tank I! through the pipe l9 and isdischarged therefrom into a suitable drain 20.

At 2|, I have indicated multiple compressed air nozzles or jets for reoving any surplus or water that may prevail on the strand prior to itsmovement from the top of the tank. The strand then passes into andthrough a trough 22 containing another compound or coatingmaterial,usually in the form of a thin fllm coating, the thickness or applicationof which is controlled by a wiper 23 of any conventional form, and insome 5 which extend from the ends cases, a wiper such as indicated at Itand later described may be employed at this point.

In the construction indicated, the compound is supplied to the trough 22from a tank or container 24 by a pump 25 driven by a motor 26 anddischarged into the trough through a jet or nozzle 21-. At 28, I haveindicated a caspan wheel operating in a water trough 29 over and aroundwhich the treated strand passes and finally is wound on a receiving reel30.

My improved dual wiper device It is indicated in detail in Figs. 2 to 5inclusive and consists of two frame members or brackets 3| which may besecured to a suitable support such for example upon the tank I 2 asindicated in Fig. 1 of the drawing. The standards in these brackets areprovided with elongated apertures 32 through which outwardly projectingstuds 33 on the frame or stock 34 of the device pass to provide verticaladjustment of the frame 34 in said brackets as well as angular ortiltingadjustment thereof, the

different positions of adjustment by nuts 33a in threaded engagementwith said studs drawing.

The frame 34 consists of a relatively large front a splash apron havinga relaplate 340 joining the front plate by side arms 34d of the rib3412, thus forming between the back plate 340 and the rib 34b and frontplate 34 a relatively large openported in the back plate 340 may passand drop back into the tank II. in this connection, it will beunderstood that the relative size of the complete frame 34 as well asthe opening 36 formed therein will be proportionate to the size desiredto be removed from the strand.

Pivotally supported on a screw or pin 38 on the outer surface of thepart 340 of the frame is a plate 39 having an outwardly extending anglemember 39a, note Fig. 5, the lower end of the jacent the pivot at 38 toengage the plate 39 to act as a stop or alinement pin to maintain theopening or threaded bore 391! of the plate 39 in proper alinement withrespect to the center of the parts 340 of the frame or the centers ofthe die 35, and the wiper element'31, or the ports or passages b and 31arespectively thereof.

Adjustably mounted in the bore 39d is a compression screw 40, the outerenlarged end of which has a plurality of radial arms 40a by means ofwhich said screw move a compression ring 4| toward and from theflexiblewiper element 31. Mounted in the threads of the screw 40 at thefree end thereof is a spring ring 40b, note Figs. 2 and 4 of thedrawing, which enters a recess in the inner end of the plate 39 andlimits the outward movement of the screw, thus preventing accidentaldisplacement of the screw 40 with respect to the plate 39 and at thesame time, permits the free swinging of the plate 39 including the screw40 into the position indias indicated in Fig. 3 of the compression ofthe I removed as with the may be rotated by hand to cated in dottedlines in Fig. 4 of the drawing in the insertion and removal of the ring4| and element 31.

The ring 4| in the construction shown in Fig. 2 of the drawing has arelatively large opening 4| a through which the conductor passes, and itis also preferable that the bore 430 of the screw 43 be large so as toprovide free passage of the conductor therethrough, whereas the bore orpassage 42 in the part 34c of the frame is preferably larger than thebore 4 a. The ring 43 has an enlarged collar 4 |b which rests upon theelement 31 and aids in forcing the central portion of said elementoutwardly into the bore 42 in the manner indicated in Fig. 2 in theoperation of reducing the size of the bore or passage 31a in saidelement.

At this time, it will be understood that as the ring 4| is forced uponthe element 31 by the screw 40, the material of the element 31 which ispreferably composed of rubber is forced into the bore or opening 42 andcompressed symmetrically therein so as to maintain the proper axis tosaid bore, and at the same time, maintain a circular opening. ,In thecompression and flexure of the element 31, it will also appear that theend of the passage 31a directed to the left or toward the bore 42 isflared.

It will also be apparent that the greater the element 31, the greaterwill be the reduction in diameter of the passage 31a, and thethickness'of the element 31 may be varied to provide a wider range ofcompression, and these adjustments of the size of the passage 31a willadopt a single element 31 to different sizes of strands. It will also beunderstood that in commercial practice, there is a wide range of wiresizes and conductor sizes employed, going into large cable sizes. Theentire device is constructed in a number of sizes consistent with thedrastic changes in diameters, whereas a single device will compensatefor numerous sizes wired within predetermined limits.

The ring 4| also includes laterally extending arms 4| 0, note Fig. 4,which extend into recesses- 43 in the frame part 34c to key the ringagainst rotation in the frame and permit only longitudinal movement withrespect to the axis of the wire in the operation of the screw 43. Thisalso avoids any possible rotation of the element 31, as will beapparent.

In Fig. 6 of the drawing, I have indicated at 44 a modified form of diewhich may be substituted for the die 35, and with this die, the bore 44athereof is provided with a plurality of inwardly projecting ribs orfingers 44b.adapted to engage the strand or conductor to centralize thesame in said die and to form by the recesses 440 between the projectingfingers 44b substantially even deposits of the compound on the strand,which deposits will be slushed into a circumferential coating of eventhickness in passing through the wiper element 31, the. surplus of thecompound being structure shown in Fig. 2 of the drawing. With thestructure shown in this figure, the die first removes part of thesurplus compound on the strand, and after passing through the element31, the compound on the strand is brought to' a finished and desiredsize with the additional surplus removed.

In Fig. 8 of the drawing, I have shown a slight modification of theconstruction shown in Fig. 2, wherein 45 indicates part of the framesimilar to a part 340, and 46 a ring similar to the ring 4|. With thisconstruction, the bore of the frame part 45 is made large and threadedto receive a plug is employed in the ring 46 being in threadedengagement therewith so that the bore 48a. of the supplemental ring maybe increased or decreased consistent with the change in the bore 41a ofthe die element 41, and at the same time, to modify the diameter of theprojecting collar portion which is formed by theflange 48b of thesupplemental ring 48." The ring lii also includes the laterallyextending arms to to key the sameagainst rotation with respect to theframe member 45, the latter being part of a frame structure similar inall other respects to the structure 7 shown in Fig. 2 of the drawing.

It will be understood that the wiper unit orthe frame 34 thereof will beadjusted with respect to its" support so as to position the severalpassages of the frame in alinement with the strand suspended between thetwo points of support, namely, the sheaves l5 and I8, or any othersupports or guides which may be provided. By maintaining the strandcentrally with respect to the passages in the wiper unit, and especiallythe element 31 thereof, the application of an even thickness coating onthe strand is made possible. It will also be understood that differenttypes of coating materials may be employed on the strand, depending uponthe results desired or required, and as previously stated, the strandmay be treated with two or more coating materials, each of which may beapplied by the use of the dual unit wiper disclosed.

It will be understood that while I have shown certain details ofconstruction for 'carrying my" invention into effect, I anrnotnecessarily limited to these details nor am I limited to the specificuse of the device herein illustrated, and various other changes in andmodifications of the construction of the device and the method of itsuse herein shown and described, may be made within the scope of theappended claims without departing'from the spirit of my invention orsacrificing its advantages.
